	effects. We show that with decreasing wall separation the quantum
	liquid goes though a sequence of confined layering transitions familiar

	and have potentially observable effects in the roton excitations
	near wave vector k∼2 Å -1. In high-density liquid 4He, 3He impurities

	A number of significant experiments have been performed in low-Earth

	the regime of large correlation lengths and tested the theoretical
	predictions to a level of precision that could not be obtained on
	Earth. Other studies have validated theoretical predictions for the

	up of the thermal equilibrium process in pure fluids near the liquid-gas

	appear, with the correlation length diverging with an exponent ν=1.},

	host one particle at most, thus implicitly allowing for hard-core
	repulsion; the pair interaction, restricted to nearest neighbors,
	is ferromagnetic, and site occupation is also controlled by the chemical
	potential μ. The models had previously been investigated by mean
	field and two-site cluster treatments (when D=3), as well as grand-canonical
	Monte Carlo simulation in the case μ=0, for both D=2 and D=3; the
	obtained results showed the same kind of critical behavior as the
	one known for their saturated lattice counterparts, corresponding
	to one particle per site. Here we addressed by grand-canonical Monte
	Carlo simulation the case where the chemical potential is negative
	and sufficiently large in magnitude; the value μ=−D∕2 was chosen
	for each of the four previously investigated counterparts, together
	with μ=−3D∕4 in an additional instance. We mostly found evidence

	to isotropic Gaussian random fields with power law spectral density
	functions. This technique is based upon the orthogonal decomposition
	of the Fourier stochastic integral representation of the field using
	wavelets. The Meyer wavelet is used here because its rapid decay
	properties allow for a very compact representation of the field.
	The Fourier–wavelet method is shown to be straightforward to implement,
	given the nature of the necessary precomputations and the run-time
	calculations, and yields comparable results with scaling behavior
	over as many decades as the physical space multiwavelet methods developed
	recently by two of the authors. However, the Fourier–wavelet method
	developed here is more flexible and, in particular, applies to anisotropic
	spectra generated through solutions of differential equations. Simulation
	results using this new technique and the well-known nonhierarchical
	simulation technique, the randomization method, are given and compared
	for both a simple shear layer model problem as well as a two-dimensional
	isotropic Gaussian random field. The Fourier–wavelet method results
	are more accurate for statistical quantities depending on moments
	higher than order 2, in addition to showing a quite smooth decay
	to zero on the scales smaller than the scaling regime when compared
	with the randomization method results. The only situation in which
	the nonhierarchical randomization method is more computationally
	efficient occurs when no more than four decades of scaling behavior
	are needed and the statistical quantities of interest depend only
	on second moments.},

  abstract = {Received 17 November 1980 In earlier work by Chen and Gasparini it
	was found that leading-order finite-size scaling for the specific
	heat of helium confined to films and pores did not seem to hold.
	We present here an analysis which includes correction-to-scaling
	terms. We do this in two ways: First, we use equations for the shift
	and value of the specific-heat maximum as suggested by Fisher. Secondly,
	we show that a bulk-plus-surface specific-heat model yields very
	similar equations for the shift and maximum, and in addition suggests
	a simple power law for the scaling function near Tλ. All aspects
	of the data can be fitted very simply with this model with only three
	parameters. We find, however, that the surface specific-heat exponent
	αs does not agree with the scaling prediction αs=α+ν. When correction-to-scaling
	terms are introduced to force agreement, we find these terms to be
	very large, larger than the leading terms, and several orders of
	magnitude larger than the equivalent correction-to-scaling amplitudes
	for bulk helium. We believe our analysis in terms of the surface
	specific heat is the first for an experimental system, and we find
	that it is quite in keeping with the spirit of some theoretical calculations.},

  abstract = {The microscopic theory of a superfluid Fermi liquid at finite temperature
	is developed for the case of a pure system with S-wave pairing, and
	applied to the calculation of the static properties. As a function
	of θ≡T/Tc these properties are determined entirely by the Landau
	parameters F0, F1, Z0, etc., characterizing quasiparticle interactions
	in the normal phase. In particular the spin susceptibility χ and
	the density of the normal component ρn are given by χ(θ)/χ(1)=(1+1/4Z0)f(θ)/[1+1/4Z0f(θ)],
	ρn/ρ=(1+1/3F1)f(θ)/[1+1/3F1f(θ)], where the universal function f(θ)≡-[ν(0)]-1Σp(dn/dEp)
	is the "effective density of states near the Fermi surface" relative
	to its value ν(0) in the normal phase. Thus the often-quoted expression
	ρn=1/3Σpp2(dn/dEp) is valid for an interacting system only in the
	limit T→0. In the latter part of the paper a simple phenomenological
	theory of "Fermi-liquid" effects on χ and ρn is developed for arbitrary
	conditions (including the presence of impurities and pairing with
	l≠0); it is found that under most circumstances explicit expressions
	for χ and ρn may be obtained which involve only the Landau parameters
	and a suitably generalized effective density of states. The theory
	should apply to the possible superfluid phase of He3 and to most
	superconductors. It is suggested that the Knight shift in nontransition-metal
	superconductors should display some "Fermi-liquid" effects. The weak-field
	dc penetration depth λ(T) is shown to be insensitive to such effects
	both in the Pippard limit and near Tc; however, in a London superconductor
	at lower temperatures the correction to λ(T) should be observable
	and yield a direct estimate of F1.},

	two-layer classical XY system with annealed impurities. The model
	Hamiltonian is appropriate for a two-layer 3He-4He mixture system.
	We find a rich variety of phase diagrams. Depending on the choice
	of parameters we find either one or two first-order phase-separation
	transitions, which may be accompanied by the appearance of superfluidity.
	Phase diagrams with two λ lines are found, making possible two distinct
	transitions in the superfluid density. In the case of phase-separation
	transitions, each transition is primarily associated with a single
	layer, and three-phase coexistence is possible. Comparison with recent
	experiments is made.},

	the long-wavelength, low-frequency dynamics of third-sound propagation

	obtains the thermodynamic quantities over a wide range of reduced

	At low temperatures it is no longer possible to consider the motion

	Such a treatment, as developed by Landau and Feynman, characterizes
	the thermal motion of the liquid by ` elementary excitations ', the
	so-called phonons and rotons. A consideration of these excitations
	then leads to the ` two-fluid ' model. It is shown that the treatment
	is adequate to account for nearly all the properties of the liquid,

	concerns the behaviour of the liquid at high rates of flow or when
	carrying a large heat current, when it is clear that some form of

  abstract = {The Berezinskii-Kosterlitz-Thouless (BKT) phase transition in two-dimensional
	planar rotator and XY models on a square lattice, diluted by randomly
	placed vacancies, is studied here using hybrid Monte Carlo simulations
	that combine single spin flip, cluster, and over-relaxation techniques.
	The transition temperature Tc is determined as a function of vacancy
	density ρvac by finite-size scaling of the helicity modulus and the
	in-plane magnetic susceptibility. The results for Tc are consistent
	with those from the much less precise fourth-order cumulant of Binder.
	Tc is found to decrease monotonically with increasing ρvac, and falls
	to zero close to the square lattice percolation limit, ρvac≈0.41.
	The result is physically reasonable: the quasi-long-range orientational
	order of the low-temperature phase cannot be maintained in the absence
	of sufficient spin interactions across the lattice.

	em função da densidade vaga ρvac pelo tamanho finito dimensionamento
	do módulo helicidade e em plano de susceptibilidade magnética. Os
	resultados do CT são coerentes com os dos cumulantes de quarta ordem
	muito menos precisa do Binder. Tc é encontrada para diminuir monotonicamente
	com o aumento ρvac, e cai para zero próximo do limite de percolação
	lattice quadrado, ρvac ≈ 0,41. O resultado é fisicamente razoável:
	a ordem de quase-longo alcance na orientação da fase de baixa temperatura
